[PATCH v8 0/2] ASoC: Intel: sof_cs42l42: adding support for ADL configuration and BT offload
1. Add BT offload fetch to cs42l42 machine driver 2. Support cs42l42+max98360a on ADL platform
V8 Changes: - split the V7 patch into two patches; one for BT offload feature, the other for new board config - change topology name to sof-adl-max98360a-cs42l42.tplg - remove useless variable 'ret' in create_bt_offload_dai_links

Add the capability to machine driver of creating DAI Link for BT offload. Although BT offload always uses SSP2 port but we reserve the flexibility to assign the port number in macro.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
